What he means is that he’s making a game engine that uses FMOD… say his engine is called engine.dll and it internally uses FMOD. The engine.dll project would be linked with fmodvc.lib, but his app project wouldn’t, since engine.dll accesses FMOD by itself.

Link your engine to fmodvc.lib, and your app to engine.lib. Your app only needs to access the engine’s functions, since the engine already knows how to use FMOD.
